FRED Pt Gen 5 Hyperfast and Ultrafast Rectifiers Increase Efficiency in Automotive, Solar, and UPS Applications

Vishay Intertechnology, Inc has introduced 15 new FRED Pt Gen 5 600V and 1200V Hyperfast and Ultrafast rectifiers in the compact SOT-227 package that are designed to increase the efficiency of high-frequency converters and of soft-switched or resonant designs. Matched to operate with MOSFETs or high-speed IGBTs, these devices released are optimized for PFC and output rectification stages for EV / HEV battery charging stations, booster stages for solar inverters, and UPS. For these applications, the rectifiers offer lower conduction losses than previous-generation devices, while maintaining low reverse recovery losses. 

The devices offer the current capability of 30 A at 600 V in the single-phase bridge configuration and 60 A to 300 A at 600 V and 1200 V in the dual-diode configuration. The rectifiers are available in X-type Hyperfast and H-type Ultrafast speed classes, with H-type devices offering the advantage of lower conduction losses and X-type devices featuring faster recovery times. These components feature high-temperature operation to +175 °C and the semiconductor in the SOT-227 package is isolated from the copper base plate, allowing for common heatsinks and compact assemblies to be built.
